Mihaela BUZARNESCU (ROU) / Raluca OLARU (ROU) v Xenia KNOLL (SUI) / Anna SMITH (GBR)
Top seed Barty is one half of last year's doubles champions here, winning the title with the now-retired Casey Dellacqua against Chan Hao-Ching and Latisha Chan, 6-4, 6-2.
All four players left in the draw are first-time semifinalists here.
Barty is actually the only one of the quartet who has competed in the main draw here previously.
The Australian is looking to emulate compatriot Samantha Stosur, the 2015 and 2017 champion here.
Buzarnescu's previous trip to Strasbourg ended with a 6-2, 4-6, 6-4 loss in the first round of qualifying to Yevgenia Savranska, back in 2008.
